6.
In a town of adults, every adult owns a car, a motorcycle, or both. If adults own cars and adults own motorcycles, how many of the car owners do not own a motorcycle?
Answer: D
Small hint:
Subtract the motorcycle owners from the total adults.
Big hint:
The adults without motorcycles are exactly the car owners who do not own a motorcycle.
Solution:
We know that people own motorcycles, so people do not own motorcycles.
Thus, D is the correct answer.
